Some scientists have proposed that the earliest forms of life may have existed in an “RNA
World” where RNA was both the genetic material and responsible for enzymatic activity.
Imagine that you have recreated such a life form. What would demonstrate that RNA, but not
protein or DNA, is necessary and sufficient for these functions?

B. The organism lives and replicates despite protease and DNase treatment, but the
organism dies when treated with RNase.

C. The organism lives and replicates despite protease treatment, but the organism dies
when treated with DNase and RNase.

D. The organism lives and replicates despite DNase treatment, but the organism dies
when treated with RNase and protease.
Feedback:Learning Objective: Analyze the process of DNA replication
